Xandra and Xanthe are a pair of two blonde-haired eight-year-old identical twin sisters who love wearing their pyjamas. Despite being identical twins, they wear different sleepwear: Xandra wears a pink long-sleeved full-body hooded kitten pyjama onesie, a pair of pink mittens, a pair of pink socks, a pair of pink slippers and a pink sleeping mask with closed eyes on it, while Xanthe wears a violet long-sleeved pyjama attire with red hearts on them, a pair of purple sleeping gloves, a pair of indigo socks, a pair of amethyst purple slippers and a violet sleeping mask. The twins are very friendly and love each other a lot.
